catch42 3 Posted December 22, 2022 Share Posted December 22, 2022 (edited) Experiencing a problem where Live TV is not being scaled to fit the screen (see photo). Doesn't happen with other sources, included recorded TV. Logs attached. ffmpeg-remux-993b6ea3-5153-46a7-bb60-2b6a5b94ceee_1.txt embyserver-63807264000.txt Edited December 22, 2022 by catch42 add photo Link to comment Share on other sites More sharing options...
ebr 14913 Posted December 22, 2022 Share Posted December 22, 2022 Hi. That is likely an issue with the TV or Roku display settings. How are they set? Link to comment Share on other sites More sharing options...

catch42 3 Posted December 27, 2022 Author Share Posted December 27, 2022 Both TVs I tried were set to the normal "fullscreen" aspect ratio. The Roku is set to "automatic", which is 1080p. Again, this only happens with Live TV broadcast in 720p. If I record the same program and play it back, it fills the screen normally. It seems to be treating Live TV programs broadcast at 720p as if they were 1080p, showing the program in the upper left with the rest of the space shown in green. Even if I change the TV aspect ratio to "zoom", the program is cutoff, because it is in the upper left, where the TV will zoom in on the center of the screen.

speechles 1917 Posted December 27, 2022 Share Posted December 27, 2022 (edited) This is a problem with the Roku firmware on some models when rendering MPEG2. The Roku will not upscale correctly for some progressive MPEG2 content. It assumes the Live TV MPEG2 stream should be interlaced then it could deinterlace on hardware which would then upscale. This is a bug in that devices firmware that upscaling cannot occur without deinterlacing when rendering MPEG2. The Emby Roku app can fix this itself. But you need to do this manually since we cannot detect when this will happen. If you press DOWN during video playback and choose the cog icon it will open Playback Settings. Inside the Playback Settings choose the "Attempt Playback Correction" button and it should solve the problem. You can use the Attempt Playback Correction multiple times, but with Live TV you should only have to do this once.

catch42 3 Posted January 5, 2023 Author Share Posted January 5, 2023 Just providing an update that using the Attempt Playback Correction did not solve the problem. Link to comment Share on other sites More sharing options...
